MANUFACTURE OF TURNED SLIPPERS OR SIMILAR FOOTGEAR Filed Feb. 14, 1947 Patented June 28, 1949 MANUFACTURE OF TURNED SLIPPERS OR SIMILAR FOOTGEAR Karl Erik Tholson, Akarp, Sweden Application February 1 4, 1947, Serial No. 728,596 In Sweden February 21, 1946 5 Claims.

In a well-known method of making simple and cheap turned slippers the upper is sewn to the sole turned inside out and is turned right after the sole is sewn on. Such slippers have no insole, but the upper is attached with the inside turned outwards direct to the outer sole by lasting and stitching operations.

It is well-known when applying such a method to the manufacture of turned slippers and similar light footgear to sew the edge of the outer sole to the edge of the upper and to a lining covering the inside of the upper, whereupon an insert or sole lining is applied to the outer sole and sewn on to the seam margin formed at the sewing together of the outer sole, the upper and the lining applied to the latter, said sewing-on taking place around the fore or toe portion of the slipper. After these operations the slipper is provided with a felt sole or the like. This is placed in the slipper by being pushed in between the sole lining sewn on around the fore portion of the slipper and the outer sole so far that the toe edge of the felt sole is adjacent the fore edge of the outer sole and the flat surface of the felt sole engages the flat surface of the outer sole. After providing the slipper with heel inserts and the like, the portion of the sole lining which was hitherto free for the insertion of the felt sole in the slipper is attached to the remaining part of the seam margin around the outer sole and the 1 upper. The felt sole placed in the slipper will thus lie free between the outer sole and the sole lining thereabove, which causes the felt sole, after some times use of the slipper, to be displaced at an angle sideways or to slide forward in the slipper owing to the non-uniform pressure of the foot, the edge of the felt sole curling up or being deformed and the good fit of the slipper being impaired. Another disadvantage is the difficulty of pushing the felt sole into the proper position in the slipper.

The principal object of the present invention is to provide a method of making light footwear such as slippers by which the above-mentioned and other disadvantages are avoided. More particularly, it is an object of the invention to provide a method of making turned slippers or similar footwear of soft material, having an upper attached to an outer sole and possibly a lining associated with said upper and a felt sole or the like provided in the slipper.

The essential characteristics of the invention are that a piece or strip of fabric or equivalent sheet material is first fastened on the felt sole in 2 the edge of the felt sole, and that said portions are then sewn or otherwise secured to the edge of the upper and/or lining before, during or after the joining of these parts with each other and with the outer sole and before the assembled slipper is turned right side out.

such a way that portions thereof project beyond The invention will be more fully described and.

illustrated in the following with reference to the accompanying drawings, in which:

Figure 1 is a perspective View of a reversed slipper made according to the invention.

Figure 2 is a perspective view of the same slipper in turned condition.

Figure 3 shows a felt sole and a strip of fabric fastened thereon.

Figure 4 is a fragmentary cross-section of the slipper according to Figures 1 and 2 in reversed condition, the section being taken along the line VT-VI in Figure 1.

Figure 5 is a fragmentary cross-section of the same slipper in turned condition.

Figure 6 is a fragmentary cross-section of a modified form of the slipper in reversed condition.

Figure 7 is a fragmentary cross-section of still another modified form of the slipper in reversed condition.

' Referring to the drawing, I designates an outer sole and 2 an upper fastened to said sole, said upper being composed of two parts of leather or any other suitable, soft material sewn together by means of seams 3a and 3b (Figure 2) at the top and at the back of the slipper, as seen in turned condition. The upper is preferably lined on the inside, in the turned condition of the slipper, with a fabric lining 4 or the like.

According to the present invention, a felt sole has a narrow strip of fabric 1 fastened to it by means of stitches 8, as illustrated in Fig. 3, said strip being applied so as to present a border portion 9 projecting at the edge of the felt sole around the whole or only the fore part of the latter. If desired, instead of the strip of fabric 1, a sheet of fabric may be provided which wholly or partly covers the felt sole. When assembling the slipper the edges of the outer sole l, the upper 2 and the lining 4 are sewn together by stitches l0 passing through all of the said elements as illustrated in Figure 4. The felt sole 6 is then fastened to the slipper by sewing the border portion 9 on to the said three elements by a row of round stitches H as shown in Figure 4. After completing this operation the slipper is turned inside out, so that the upper 2 and the lining 4 adjacent the edge of the outer sole l will occupy the position shown in Figure 5. If desired, a cover sole I2 is inserted and fastened in the slipper, and then the slipper is ready to undergo the remaining well-known finishing operations. As will be understood, the felt sole 6 is fastened to the slipper through the intermediary of the strip 1 and cannot change its position therein during the wearing .of the.- sli;');per.

Figure 6 shows a modified method of joining the elements I, 2, 4 and 6. The outer sole l, the upper 2 and the lining 4 are sewn together at their edges similarly as in Figure-gl nt the lining 4 is allowed to project beyond the flush edges of the sole l and the upper 2. The felt sole 5 is fastened to the elements I, 2 and 4 by meansof stitches is through the strip :horder portion :13 and the projecting margin I' l of theli'ning.

It will be clear, that the joining of the various parts need not take place in the order stated above, although this is the simplest way of doing it. In a-modification, however, which is illustrated in l fi-gure 7, the outer sole l 'a'ndthe upper-21mphout the lining) are first sewn together by'stitches I'S'and the lining 4 and the'stripbo'rder portion 9 of the felt sole are similarly sew-ntogether by stitches l6. Then all'four elements are joined together by means ofstitches lTthrough'the sole, the upper and the lining behind the stitches asshowninl 'igure'if H L Whichever of the above methods of joining the elements according to theinv'ention is used, a fewer number of operations are -nee'ded for the manufacture than when the well-known method outlined above is used. Furthermore the inven tion involves a saving of materials. Itfwi ll be understood that the invention is capalole of still further modifications and therefore is:"notitelbe thereof as described and illustrated.
